Answer:
a) The speed of the block immediately after the collision is 
.
b) The impulse exerted on the block is 
.
Explanation:
Hi
a) As this is a perfectly elastic collision, we can use the formula 
, due 
, we obtain 
. Then with the data that we know 
and 
, therefore 
or adding uncertainty.
b) Now that we know the speed we can use 
Answer:
Explanation:
Temperature is the measure of average kinetic energy or energy in motion in a molecules. Brownian motion measure kinetic energy or how energetic the motion is and it is proportional to temperature.
Therefore, an increase in Temperature will bring about increase in kinetic energy of brownian motion. It will speed it up.
